The SFC332 is a dual meter bi-directional field

mounted flow computer which can be used for all liquid and

gas applications, including custody or non-custody

measurements. Using orifice plate, Venturi,

turbine/PD/ultrasonic mass meter, or wedge devices, it can

meter a wide variety of products, such as crude, refinedproduct, LPG/NGL products, products that use table 24C,

ethylene, propylene, and water. Fifty days of previous daily

data, fifty previous batch data, and fifty previous hourly data

are stored in the full format type reports. The previous 100

audit trail reports and 100 alarm reports are stored. User

formatted reports and user formatted ticket reports are

available.

Sixteen different product files are user-configurable

and stored in memory with an easy switch feature to enable

the user to choose which product is being monitored at any

given time. Product scheduling for batch operation is also

available.

SFC332P

SFC332P prover flow computers store data for up to 60 meters and can easily be configured from

inside a vehicle with a laptop. With the push of a button proving is initiated for any of the 60 meters.

The flow computer controls the proving process and generates all the proving reports. When proving

is complete a printed report is automatically generated to a serial printer port. The data can also be retrieved

via a laptop at any time.

The SFC332P can be mounted on a prover trailer, which can be moved from field to field to provide

proving services.
